Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F. Toss 1 lb diced eggplant, 12 oz diced zucchini, 1 large diced red bell pepper, and 1 medium diced yellow onion with 3 tbsp olive oil, 1 tsp kosher salt, and 1/2 tsp black pepper on a large rimmed baking sheet. Spread in a single layer.
  2. Step 2: Roast vegetables for 25 minutes, stirring halfway through, until tender and edges are caramelized.
  3. Step 3: While vegetables roast, heat 1 tbsp olive oil in a large skillet over medium heat. Add 4 minced garlic cloves and sauté for 30 seconds until fragrant.
  4. Step 4: Stir in 1 1/2 cups canned crushed tomatoes, 1/4 cup chopped fresh basil, and 1 tbsp chopped fresh thyme. Simmer for 10 minutes, stirring occasionally, until the sauce thickens and flavors meld.
  5. Step 5: Combine roasted vegetables with the tomato sauce in the skillet and cook together for 3 minutes to marry flavors. Adjust seasoning with salt and pepper to taste.
  6. Step 6: Serve warm as a main or side dish, garnished with extra fresh basil if desired.
